1413798 Analogue computers for economic systems T X LEWIS 5 Jan 1973 [6 Jan 1972] 615/72 Heading G4G A bridge circuit for simulating economic situations provides a model of the "inflation equation" K 1 W/K 2 P = 1-n when the boundaries of which are fixed by and which is a function or mathematical model of a chosen national economy and is generated by from a set of variables representing at least those stated above, and where P is gross national product, K 1 is wage factor, K 2 is price factor, D 1 is internal demand, D 2 is external demand, P r is productivity and W is workforce. The variables W, P, K 1 and K 2 are simulated by the voltages in the arms of the bridge, e.g. as indicated in Fig. 1, by manually or automatically adjustable impedances, valves, transistors, resistances, &c. The function generator FG is designed, according to known methods, to calculate n = profit level from any chosen number of relevant variables (D 1 , D 2 , P and P r being essential), the input variable P being derived through an amplifier A from arm 7 of the bridge. The-output of FG, which represents n, is fed to the grid of triode 3a and changes the resistance of the arm 5 (representing K 2 ) of the bridge. The voltages developed in arms 6 and 7 (representing W and P) are amplified and fed to respective coils 12, 11 and any unbalance causes contact 13 to move and to actuate either servo-motor 10 or servo-motor 4 which respectively control sliders 1 and 2. The Specification also describes modifications of the bridge circuit for revolving specific problems all subject to the same inflation equation.
